HIGHLY ABRASION RESISTANT INTEGRATED SPACERS
pau wrap® Spacers
TDC’s pau wrap® Spacers are designed as an efficient sacrificial composite collar to protect pipelines that are inserted into microtunnels and casing pipes. These highly abrasion-resistant integrated spacers are designed in a unique way, to distribute the weight of the pipes as they travel through the tunnels and can be integrated seamlessly into our pau wrap® TL products or used on a standalone basis. During the installation, they enable the pipeline to stay at a minimum distance from the casing or tunnel internal surface and take on the full abrasion against the stresses caused by the pull forces and friction.
The exact design parameters for a pau wrap® Spacer are determined jointly between our technical team and the clients’ engineering team. The pau wrap® Spacers’ shape, thickness and wear properties can all be tailor-made to accommodate a project’s requirements and technical constraints, ensuring a perfect fit and optimal performance.
